Kofi Annan: the UN's 'rock star' secretary-general

Kofi Annan, who died Saturday at the age of 80, led the United Nations through the divisive years of the Iraq war and the trauma of the September 11, 2001 attacks. The first secretary-general from sub-Saharan Africa, Ghanaian-born Annan was credited for raising the UN’s profile during his two-term tenure, from January 1997 to December 2006. The charismatic, quiet-spoken career diplomat will be remembered as the United Nations’ star secretary-general — and arguably the world body’s most popular leader.
